有没有办法自动启动Primefaces中的进度栏​​？

Question

I have a progressbar which is rendered based on a dropDownMenu value. After loading the progressbar, I need to start it somehow automatically or any workaround?

<p:progressBar widgetVar="pbAjax" ajax="true" value="#{myBean.progress}"
                                           labelTemplate="{value}%" styleClass="animated" global="false"/>

Answer 1

To start progress bar:

PF('pbAjax').start();

Answer 2

You'd like to show the progressBar when user changes item? I guess you use a Primefaces dropdown. If so, add the onChange attribute on your dropdown and start the progress bar by PF('pbAjax').start();
